TO ALL WHOM IT MAY CONCERN:

Be it.known that I, D. LA..GILBERT, of Morristown, in the county of Lamoille, audio the State ofVermont,` have invented certain new and useful Improvements in Butter-Tubs; and do hereby declare that the following issn. full, clear, arid exactdescrptionthereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. A I

In the annexed drawings, inaking part of this specification', -A represents ya. butter-tub of any approved construction, and B represents its lid or cover. v i

C C represent three or more metallic hooks, which are secured to the tub upon its outside, and near vits upper edge, the upper end of the hook extending above said edge. The cover B has t ree or more slots or openings, D D, cut 'in its rim, and ou one side of Veach of these slots the wood of the rirn isbeve-lled off', or an inclined surface is formed, as seen, from a to a. Ast-he rim of the cover projects beyondthe edges of the tub, it is necessary that the slots D D should be cut in it, in order to4 allow it to passv over-the upper ends of the hooks o c. y l

When the cover has been placed upon the tub, and partially rotated, the inclined or. bevelled portion of the rim, from a to a, catches under the upper lip of thehook's, and secures it firmlyupon the tub.

.By turning the cover suiiiciently, thc inclined surfaces upon its riiu` will tighten it lupon the tub, so as to entirely exclude air. Any suitable packing may be used with it.

Having thus fully described iny invention, what I claim as new, and desire to Asecure by Letters Patent, is-

The hooks C C upon the tub, when'used in combina-tion with the cover, provided'with slots D D and'the inclined surfaces, from t to a, as and for the purpose set forth. v

In testimony that I claim the foregoing, I have-hereunto set my hand, this'l25th day of May, 1868.-

D. A. GILBERT.
